To all fr0/wm t 'may concern.'

Be it known that I, VICTOR WILLOUGHBY, residing at Ridgewood, Bergen County, New Jersey, and being a citizen of the United States, have invented certain new and useful Improvements in a Car-Truck Side Frame, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and tov use the same, reference being had to the accompanying drawings, which illustrate the preferred form of the invention, though it is to be understood that the invention is not limited to thev exact details of construction shown and'y described, as -it is obvious that various modifications thereof within the scope of the claims will occur to persons skilled in the art.

In said drawings:

Fig. 1 is a view in side elevation of a car truck side frame constructed in accordance with this invention, the truckbolster being shown; in position and the wheels and axles indicated by broken lines;

Fig. 2' is a top plan view, partly broken away, of the side frame and bolster;

Fig. 3 is a transverse section taken on the line 3-,5 of Fig. 1, the bolster being shown in outline;

Fig. 4 is a vertical section taken on the line 4-4 of Fig. 2, partly broken away, and the bolster omitted; and

Fig. 5 is a fragmentary section showing a modified means of bracing the upper ends of the'webs of the bolster column members.

It is an object of this invention to provide an improved car truck side frame of the arch bar type and, more particularly, to provide an improved side frame of the type described wherein the bolster column members are formed with projecting portions which seat upon the tension member of the side frame and cooperate to form a seat for the spring plank. It is also an objectof this rin-Y` vention to provide' animproved car truck side frame which may be readily assembled and disassembled and in-which the bolster column members are securely held in position by means which may be readily withdrawiiin combination with a minimum num-l ber of rivets.` j n lVith these andl other objectszin view this invention comprises a car truck side frame having a compression member 1 and aten# slightly above' the end portions 3, while the tension member 2 has its depressed central portion curved.

Mounted in the opening between the compression member 1 and the tension member 2 are spaced cast bolster column members 7 and 8 of channel-shape with their webs 9 and 10 facing each other and their Hanges 11- and 12 extending outwardly, the flanges bei-ng longer than the webs and extending above the compression member 1 and below the tension'r member 2 and tie bar 6. The upper ends of the iianges are joined by connectmg pieces 13 and 14 integral with the flanges and provided with openings in which are inserted the rivets 15 which secure the upper ends of the bolstercolumn members to the compression member 1, while through openings in the lower ends of the iianges are passed bolts 16 and 17 which engage beneath the tie bar 6, the tie bar, between the bolts 16 and 17, beingcurved to coliform to the curvature of' the tension member 2 and being held in engagement therewith by the bolts 16 and 17.

Formed integral with the bolster column members 7 and 8 are. the portions 18 and 19 which project inwardly from lower-'ends of the column members, the 4portions 18 and 19 being provided with downwardly opening channels or grooves having curved bottom surfaces 1SEl and 19@L which conform to the curvature of the tension member 2 and are adapted to engage therewith when the inner surfaces of thel projecting portions are in engagement as at V20. rlhe projecting portions 18 and 19 are also .provided with flat upper surfaces 21 and 21a which cooperate to form a seat for the spring plank 22 andy have upwardly projecting bosses 23 which engage in openings 24 inthe spring plank. The engagement of the Abosses in the openings in the spring plank serves to retain the spring plank in position' while also serving to aid in retaining the bolster column members in position. Openings 26 and 2T are formed in the projecting portions 18 and 19 which aline with openings 28 and 29, respectively, in the tension member 2 when the bolster column members are in position and dowel pins 30 engaging in the openings in the portions 18 and 19 and the tension member 2, aid in positioning the bo;ster column members, the dowel pins being held in the openings bj; the tie bar 6 and the spring plank 22 which closes the openings at the bottom and top.

The Webs 9 and 10 ol the .bolster column members T and S are connected b v a plate 31 provided with ilanges 32 which engage over the upper ends ot the webs and aids in positioning the bolster column members. To the inner flanges 11 and 12 are secured the brackets 33 and 31 in which are mounted the usual brake hangers 35 and 36. The upper portions ot the webs 9 and 10 are shaped to provide tlat surfaces tor engagement with the usual bolster guide members 23T and 3S which are secured to the usual bolster 3.() and guide it in its movement in the bolster opening between the column members T and S. Vl`he usual springs which rest upon the spring piani.: 22 and support the bolster 35) are omitted l'rom the drawings.

ln the modified construction shown in Fig. 5 the web 10 ot the bolster column member is long enough to engage with the compression member 1 when the bolster column members are in position and the upper end ot the web is braced b V means oi" a plate 11 which lies between the llanges il-2 and is secured to the compression member 1 b v the rivet 15. Otherwise the construction or' this modification is as shown in Fig. 4.

ln assembling the side tra ne shown 'in Figs. 1 to the compression member 1 is slipped through the openings between the upper ends ol' the webs 9 and 10 oi' the bolster column members 'T and S, respectively. and the cross pieces 13 and 11 which join the upper ends of the flanges 11 and 12, respectively. The bolster column members 7 and S are moved along the con'ipression member 1 until the rivet openings in the compression member 1 and the cross pieces 13 and 11 are in line, the column members 't' and S are then swung outwardlj,Y and the plate 31 placed against the compression member 1 and secured in position by swing ing the bolster column members back to the position .shown in Fig. l with the upper ends the webs 9 and 10 engaging the ilanges 32 of the plate 31 and the inner surlices of the portions 1S and 19 in engage ment 20. rThe tension member 2 and the tie bar G are then brought into position against the bolster column members and held bj; the bolts 1G and 17 and the dowel pins 30. The rivets 15 are then inserted and the journal boxes placed between the ends ot the members and held in position by the journal box bolts 5.

' The structure shown in Fig. 5 is assembled in the same manner the structure shown in Fig. 4E except that the plate 81 ot' Fig. 4 is omitted and the plates il1 added as the rivets 15 are inserted.
